Class InlineBeforeAnalysisPolicy

java.lang.Object

com.oracle.graal.pointsto.phases.InlineBeforeAnalysisPolicy

public abstract class InlineBeforeAnalysisPolicy
extends Object

Provides the policy which methods are inlined by InlineBeforeAnalysis. If InlineBeforeAnalysisPolicy.shouldInlineInvoke(org.graalvm.compiler.nodes.graphbuilderconf.GraphBuilderContext, ResolvedJavaMethod, org.graalvm.compiler.nodes.ValueNode[]) returns true for an invocation, the graph decoding goes into callees and starts decoding. A new scope is opened for each callee so that the policy implementation can track each inlined method. As long as InlineBeforeAnalysisPolicy.AbstractPolicyScope.processNode(com.oracle.graal.pointsto.meta.AnalysisMetaAccess, ResolvedJavaMethod, org.graalvm.compiler.graph.Node) returns true, inlining is continued. If InlineBeforeAnalysisPolicy.AbstractPolicyScope.processNode(com.oracle.graal.pointsto.meta.AnalysisMetaAccess, ResolvedJavaMethod, org.graalvm.compiler.graph.Node) returns false, the inlining is aborted. If InlineBeforeAnalysisPolicy.AbstractPolicyScope.processNode(com.oracle.graal.pointsto.meta.AnalysisMetaAccess, ResolvedJavaMethod, org.graalvm.compiler.graph.Node) returns true for all nodes of the callee, the inlining is committed.
